With the 2012 Specialty Equipment Market Association (SEMA) Show in full swing, Mazda lifted the wraps off three new concept versions of its CX-5 compact crossover to demonstrate the personalization choices owners have, and in one case, to highlight the diesel option that may soon be available in North America.

We will start with the latter that is named after actor and Mazda racecar driver Patrick Dempsey and which uses the Japanese brand's European-specification SKYACTIV-D 2.2-liter clean diesel engine to power the all-wheel-drive system through a six-speed manual gearbox.

The four-cylinder unit has an output of 175hp (129kW) at 4,500 rpm and 310 lb-ft (420Nm) of peak torque delivered from 2,000 rpm.

Moving on to the next study, the West Coast-themed CX-5 180 was designed for sports enthusiasts and aside from the custom paint job and 20-inch alloys with all-season Goodyear Eagle F1 Asymmetric 265/40R20-sized tires, it gets a special roof rack equipped with Burton Cheetah snowboards and a Rusty surfboard, plus a bespoke interior treatment.

Last but not least, since it's probably the best looking of the three studies, is the CX-5 Urban. It's body is shrouded in a two-tone matte finish that features multi-dimensional shadows, while Mazda also equipped the crossover with customized wheel flare extensions to fit the 22-inch Ace Alloy Scorpio matte black wheels and Nitto Tire NT420s 295/30R20 all-season tires. The CX-5 Urban also features a Racing Beat dual exhaust.
